Antireflection Coatings

REO designs and produces a tremendous variety of antireflection coatings to meet a wide range of needs in terms of performance, durability, stability and cost. We particularly specialize in meeting difficult performance targets, such as very low (<0.03%) reflectivity, multi-wavelength response, broadband coverage or high angle of incidence operation. Plus, we can employ ion beam sputtering (IBS) technology when you need the ultimate in terms of environmental stability, mechanical and chemical (abrasion, salt fog) durability.

Thin Film Engineering

REO Thin Film Engineering is the core technology of our company. Collectively, our engineering team has well over 100 years of TF manufacturing and design experience. We strive to be an extension of your own engineering and product development organization. We leverage our experience to provide you with the most efficient and robust solutions for your component and assembly requirements.

Thin Film Coating

Over 20 years ago, REO became the first company to commercially provide Ion Beam Sputtered (IBS) thin film coatings. Today, we have expanded our technology to produce the highest quality thin films performing a range of functions across the full optical spectrum from the deep UV (190nm) through the long wave IR (14um). With a total of 35 coating chambers in operation, REO’s ability to produce the highest performance, lowest loss, most durable thin films across the spectrum is unmatched in the world.

High Laser Damage Threshold Optics

REO consistently delivers optics with exceptional laser damage resistance characteristics because we fabricate, coat and laser damage test our products under highly controlled processes in our state of the art facility in Boulder, CO. REO is unique because of our broad well-equipped in-house laser damage testing lab with several different laser pulsewidths and wavelengths. This vertical integration is critical because reliably achieving high damage threshold requires careful control over every aspect of the design and manufacturing process. This includes precise specification and thorough inspection of incoming raw materials, followed by shaping and polishing of components in a way that minimizes subsurface damage and contamination. We then design and deposit thin film coatings using techniques that avoid contamination and minimize electric field effects.

Facilities

Our factory has been built and organized for optics, thin film coatings and assembly fabrication. Clean rooms, state of the art metrology and our laminar flow production areas for contamination controls are just the foundation of what we do to ensure excellence.
